The mounting stage 16 is moved up and down. Note that the tray transfer stage 16 and the respective stacking cassettes 11 and 13 are moved up to the tray transfer height position H2 so that the single tray 7 accommodated in the tray transfer stage 16 is moved to the stage 16. Or a delivery means (mechanism) (not shown) for delivering one tray 7 held on the stage 16 to the stacking cassette 13 is provided.

  The second tray supply device 20 has the same configuration as the first tray supply device 10 having the above-described configuration, and includes a supply-side stocker unit 22 equipped with a stacking cassette 21, a stacking cassette. 23 is provided with a collection side stocker unit 24 equipped with 23 and a tray transfer device 25. In the first tray supply device 10, for example, a tray 7 for supplying components mounted on the source side terminal portion is accommodated in the liquid crystal panel substrate 1, and in the second tray supply device 20, a gate is provided. A tray 7 for supplying components mounted on the side terminal portion is accommodated.

  In the component mounting apparatus 100 having such a configuration, first, the liquid crystal panel substrate 1 carried in by the panel board carrying-in device 5 is placed on the panel placement stage 2 (step S1 in the flowchart of FIG. 9). At the same time, it is confirmed whether or not the tray 7 is arranged at the component supply position P10 (step S2). When the tray 7 is not disposed, the tray transfer stage 16 is moved and positioned at the tray supply position P11 by the stage moving device 18 in the first tray supply device 10, and then the tray is moved by the stage lifting device 17 to the tray. As the transfer stage 16 is raised to the tray transfer height position H2, one tray 7 is supplied from the supply side stocker unit 12 to the tray transfer stage 16 (step S5). Thereafter, the tray transfer stage 16 is lowered to the stage moving height position H1, and further moved to the component supply position P10 for positioning.

  Next, one component is sucked and taken out from the tray 7 positioned at the component supply position P10 by the reversing head unit 8 and reversed in the vertical direction, and then the component is delivered to the temporary head unit 3 (step). S6). Thereafter, the component held by the temporary attachment head unit 3 is aligned with the mounting position of the component on the source-side terminal unit of the liquid crystal panel substrate 1 placed on the panel placement stage 2. Components are mounted (temporarily attached) by the head unit 3 (step S7). Such operations of the reversing head unit 8 and the tacking head unit 3 are sequentially repeated, and components are mounted on the source side terminal unit. The reversing head unit 8 is provided with a recognition camera 8a for recognizing the position of the component stored in the tray 7, and the component is taken out based on the recognition result by the recognition camera 8a. Further, the tacking head unit 3 is provided with a recognition camera 3a for recognizing the mounting position of the component on the liquid crystal panel substrate 1, and the component is mounted based on the recognition result by the recognition camera 3a.

  On the other hand, in the 2nd tray supply apparatus 20, the same operation | movement of the tray mounting apparatus 25 is performed, and it is set as the state by which the tray 7 was located in the component supply position P20. When the mounting of the components on the source side terminal portion is completed, the liquid crystal panel substrate 1 placed by the panel placement stage 2 is rotated 90 degrees in the XY plane. At the same time, the components supplied from the tray 7 located at the component supply position P20 are sucked and held by the temporary head portion 3 via the reversing head portion 8 and mounted on the gate side terminal portion of the liquid crystal panel substrate 1. The

  If it is confirmed in step S2 that the tray 7 is arranged at the component supply position P10 (P20), it is determined whether the arranged tray 7 is empty (step). S3) In the empty state, after the empty tray 7 is moved to the tray collection position P12 by the tray transfer device 15 (25), it is empty to the tray delivery height position H2 by the stage elevating device 17. As the tray 7 is raised, the empty tray 7 is collected in the collection side stocker unit 14 (step S4). Thereafter, a new tray 7 is supplied from the supply side stocker unit 12 and is arranged at the component supply position P10, so that the component supply is continuously performed (step S5).

  When the mounting (temporary attachment) of the components to the liquid crystal panel substrate 1 is completed, the liquid crystal panel substrate 1 is transferred from the panel mounting stage 2 to the panel substrate carry-out device 6 and carried out from the component mounting device 100 (step S8). . After the carry-out, it is determined whether or not the next liquid crystal panel substrate 1 is produced, that is, mounted (step S9). If the mounting is performed, the next panel substrate 1 is carried in ( Step S1).

  Next, a configuration for replenishing a new tray 7 and taking out and collecting an empty tray 7 in the stacked tray supply apparatus 101 of the present embodiment will be described. In describing this, a schematic side view of the stacking tray supply apparatus 101 in the X-axis direction is shown in FIGS. 4 and 5, and a schematic side view in the Y-axis direction is shown in FIGS. 6 and 7. In addition, since the 1st tray supply apparatus 10 and the 2nd tray supply apparatus 20 have the same structure, in the following description, the 1st tray supply apparatus 10 is demonstrated on behalf of each tray supply apparatus. Shall be performed.

  As shown in FIG. 4, in the tray transfer device 15 that is a movable configuration in the first tray supply device 10, the tray mounting stage 16 is translated (horizontally moved) along the Y-axis direction by the stage moving device 18. However, this movement is performed in a state where the tray mounting stage 16 is positioned at the stage moving height position H1. Accordingly, the parallel movement of the tray mounting stage 16 is performed within the movement region (movement range) R shown in FIG. In the first tray supply device 10, the stacking cassettes 11 and 13 are supported above the moving region R so as not to interfere with the moving region R.

  In the tray supply apparatus of the first embodiment, such a movement region R of the tray mounting stage 16 and a region in which the respective stacking cassettes 11 and 13 are installed can be separated (or blocked). The structure which can do is provided. Specifically, as shown in FIGS. 4 to 7, in the supply side stocker unit 12, the lower side opening (the opening for supplying the tray) of the stacking cassette 11 and the movement of the tray mounting stage 16 are moved. A safety cover device 40 (an example of a blocking device) that releasably blocks the communication space with the region R is provided. The safety cover device 40 is a safety cover 41 formed, for example, in the shape of a square plate in such a size that the space can be blocked by a material that is thin and lightweight (for example, a thin iron plate or resin plate) that is capable of maintaining its own form. And a safety cover opening / closing part 42 that opens and closes the safety cover 41 while supporting the safety cover 41 at one end thereof. The safety cover opening / closing part 42 is configured using, for example, a cylinder mechanism that is driven in the vertical direction. The safety cover 41 is opened by placing the safety cover 41 on the YZ plane. By rotating 90 degrees by the mechanism, the safety cover 41 is placed on the XY plane so as to be in a closed state (that is, a cut-off state). Such a safety cover device 40 is similarly provided in the collection side stocker unit 14. Since the first tray supply device 10 is provided with the safety cover device 40, when the stacking cassettes 11 and 13 are exchanged in the stocker units 12 and 14, the stacking cassettes 11 and 13 are replaced. The replacement work area can be completely separated from the movement area R of the tray transfer stage 16, and it is possible to prevent an operator from accidentally putting a hand or a tool into the movement area R.

  Further, as shown in FIGS. 4 to 7, the first tray supply device 10 is surrounded by a casing 50 in order to prevent inadvertent access from the outside from the viewpoint of safety. In order to exchange 11 and 13, an upper cover 51 is provided at the top thereof so as to be openable and closable. Further, as shown in FIGS. 5 and 6, the stacking cassette 11 provided in the supply-side stocker unit 12 is placed between the tray 7 and the tray mounting stage 16 positioned at the tray transfer height position H2. The retraction height at which the contact between the equipment height position H3 where the delivery is performed and the tray placement stage 16 positioned at the tray delivery height position H2 as shown in FIGS. 4 and 7 is reliably prevented. It is configured to be selectively fixed and supported between the head position H4. That is, in the supply-side stocker unit 12, the mounted stacking cassette 11 can be fixedly supported at the installation height position H3 where the tray 7 is supplied, and further fixed at the retreat height position H4 above it. It can be supported. Such selective switching of fixed support at two height positions, that is, raising and lowering of the stacking cassette 11 can be performed using an automatic mechanism, but in the first embodiment, an operator can This is done by manually lifting and lowering the stacking cassette 11. In addition, a lock mechanism (not shown) is provided to fix the support position at each of the height positions H3 and H4. The collection side stocker unit 14 has the same configuration as the supply side stocker unit 12 and includes a separate safety cover device 40 that can be opened and closed independently.

  4 and 5, in the supply-side stocker unit 12, tray detection means for detecting that the storage quantity of the tray 7 in the stacking stocker 11 is equal to or less than a predetermined quantity, for example, the storage quantity is A supply-side sensor 61 that detects that the number of sheets has reached zero is provided. Further, in the collection side stocker unit 14, tray detection means for detecting that the storage quantity of the tray 7 in the stacking stocker 13 exceeds a predetermined quantity, for example, the collection side detecting that the storage quantity is full. A sensor 62 is provided. The detection results by these sensors 61 and 62 are configured to be input to the control device 60 that controls the operation of the stacking tray supply device 101. In the supply side stocker unit 12, the supply side sensor 61 detects that the number of stored trays has become zero, or in the collection side stocker unit 14, it indicates that the number of stored trays is full. When detected by 62, a warning prompting replacement of the stacking cassette is displayed on the display 63, which is an operation display unit in the control device 60, so that the detected stocker unit can be identified (the display of FIG. 8). 63 display example (referred to as “tray replacement”). Note that such warning display for prompting replacement of the stacking cassette is not only displayed on the display 63 but also displayed on the display unit 64 provided in the supply side stocker unit 12 and the collection side stocker unit 14. It may be the case. Thus, by displaying the warning prompting the replacement of the stacked cassette on the display 63, it is possible to prevent the operator from trying to access the stocker unit other than the replacement target by mistake. In particular, by displaying such a warning on the display unit 64 provided in the exchange target stocker unit, the operator can more easily recognize the exchange target stocker unit.

  In the component supply apparatus 100 including the stacking tray supply apparatus 101 having the above-described configuration, a tray replacement, that is, a stacking cassette replacement procedure will be specifically described. In this description, schematic explanatory views showing the state of the stacking tray supply device 101 in each procedure are shown in FIGS. 10 to 14, and flowcharts showing the replacement procedure are shown in FIGS. 15 and 16.

  First, in step S11 of the flowchart of FIG. 15, the normal component mounting operation is continued in the component mounting apparatus 100. In such a state, it is determined whether or not the collection side stocker unit 14 is full with the empty tray 7 (step S12). Specifically, it is determined by the collection side sensor 62 provided in the collection side stocker unit 14 whether or not the empty tray 7 stored is full. When it is detected that the storage is full, the fact is displayed on the display 63 of the control device 60 by identifying the target stocker unit 14, and the operator replaces (takes out) the stacking tray. Is prompted.

  On the other hand, if it is confirmed that the collection side stocker unit 14 is not full, it is next determined whether or not the supply side stocker unit 12 is empty (step S13). Specifically, whether or not the tray 7 remains is determined by the supply side sensor 61 provided in the supply side stocker unit 12. When it is detected that the state is empty, the fact is displayed on the display 63 in the control device 60 by identifying the target stocker unit 12, and the operator is requested to replace (replenish) the stacking tray. Prompted.

  In step S20 of FIG. 16, when the operator starts the stacking tray replacement operation, it is first confirmed whether or not the tray transfer stage 16 is positioned outside the interference area (step S21). Specifically, in the first tray supply device 10, the tray transfer stage 16 is not positioned at the tray supply position P11 and the tray collection position P12, that is, is positioned below the stocker units 12 and 14, respectively. It is confirmed that it is not. In such a case, the tray transfer stage 16 is moved out of the interference area, preferably to the component supply position P10.

  If it is confirmed in step S21 that the tray transfer stage 16 is located outside the interference area, the safety cover 41 is moved by the safety cover opening / closing unit 42 in the stocker unit 12 (or 14) to be replaced. It is turned to a closed state (step S23). Specifically, as shown in FIG. 10, the opened safety cover 41 is rotated and closed as shown in FIG. 11, and the stacking cassette 11 (or 13) is moved to the tray. The moving stage R is blocked from the movement area R of the mounting stage 16. Note that after the blocking by the safety cover 41 is performed as described above, the movement restriction of the tray transfer stage 16 is released, and the movement within the movement region R can be freely performed.

  Thereafter, the closing lock by the upper cover lock portion 55 of the upper cover 51 is released (step S24), and the upper cover 51 is opened as shown in FIG. 12 (step S25). In such a state, the safety cover 41 blocks the communication of the tray transfer stage 16 to the moving region R, thereby preventing an operator from accidentally accessing the region R.

  Next, as shown in FIG. 13, the stacking cassette 11 (or 13) is lifted from the equipment height position H3 to the retracted height position H4 and supported and fixed at this height position (step S26). The support position of the stacking cassette 11 (or 13) is fixed by the support position of the stacking cassette 11 (or 13) being locked by the vertical lock lever 56. When the stacking cassette 11 is positioned at the retreat height position H4 as described above, the tray transfer stage 16 ascends through the safety cover 41 to the tray transfer height position H2 due to, for example, the occurrence of a malfunction. Even if such an abnormal situation occurs, the stacking cassette 11 is positioned at the retreat height position H4, so that they can be prevented from contacting each other.

  Thus, in the state where sufficient safety for the worker is ensured and the movement limitation in the movement region R of the tray transfer stage 16 is released and the component supply operation, that is, the component mounting operation is continued. As shown in FIG. 4, the stacking cassette 11 (or 13) is replaced, that is, a new tray 7 is replenished (or the empty tray 7 is taken out and collected) (step S27).

  Thereafter, the exchanged stacking cassette 11 (or 13) is lowered from the retracted height position H4 to the equipment height position H3 and supported and fixed (step S28), and the upper cover 51 in the opened state is closed ( In step S29, the upper cover 51 is locked in the closed state (step S30). Then, the safety cover 41 is opened by the safety cover opening / closing section 42 (step S31), and the stacking tray replacement operation is completed (step S32). It is more preferable to open the safety cover 41 after confirming that the tray transfer stage 16 is outside the interference area, as in steps S21 and S22.

  In the above description, the stacking tray replacement operation in the first tray supply device 10 of the stacking tray supply device 101 has been described. However, the second tray supply device 20 performs the stacking tray replacement operation by the same operation. be able to.

  In addition, the case where the stacking trays are replaced by replacing the stacking cassettes provided in the stocker unit has been described as an example, but this embodiment is only for such a case. It is not limited. In place of such a case, for example, the tray itself may be replaced (replenished / recovered) without replacement of the stacking cassette.

  Further, the components stored in the tray 7 supplied from the first tray supply device 10 are mounted on the source side terminal portion of the liquid crystal panel substrate 1 and stored in the tray 7 supplied from the second tray supply device 20. However, for example, the tray 7 supplied from the first tray supply device 10 and the second tray supply device 20 supply the components. There may be a case in which common parts are included in the tray 7 to be used. In such a case, when the tray 7 arranged at the component supply position P10 of the first tray supply device 10 becomes empty, the tray 7 is arranged at the component supply position P20 of the second tray supply device 20. While switching to the component removal from the tray 7 so that the component supply can be continued, the first tray supply device 10 collects the empty tray 7 and arranges the new tray 7 at the component supply position P10. You can also. For example, in the first tray supply device 10, the tray 7 can be supplied from the second tray supply device 20, that is, the components can be supplied when the stacked trays are exchanged. In such an operation, the supply of components can be continued from the other tray 7 while the empty tray 7 is being replaced, so that the production efficiency can be further improved.

  In the first embodiment, the case where components are mounted (temporarily attached) to the liquid crystal panel substrate 1 has been described as an example. However, instead of such a case, for example, a general circuit board is used. It may be a case where the mounting of the component to is performed. In such a case, for example, the same type of components are stored in the tray 7 stored in the first tray supply device 10 and the second tray supply device 20 so that the two component supply systems are By alternately using, productivity can be improved.

  According to the first embodiment, in each of the stocker units 12 and 14, the space in which the stacking cassettes 11 and 13 are equipped and the moving region R in the horizontal movement of the tray transfer stage 16 are cut off and separated. Since the safety cover 41 is provided, it is possible to reliably prevent an operator from accidentally accessing the moving region R when replacing the stacking tray. It is valid.

  Further, in each stocker unit 12, 14, the stacking cassettes 11, 13 are moved up to the equipment height position H 3 where the tray 7 is transferred to and from the tray transfer stage 16, and the tray transfer stage 16 is raised. Even in this case, the operator selectively holds the stacking cassettes 11 and 13 at the respective height positions with respect to the retreat height position H4 that is the position where the contact with the tray transfer stage 16 is prevented. By adopting a configuration capable of supporting and fixing, the stacking cassettes 11 and 13 are exchanged in a state where the stacking cassettes 11 and 13 are supported and fixed at the retreat height position H4. Thus, for example, an abnormal situation in which the tray transfer stage 16 rises through the safety cover 41 to the tray transfer height position H2 due to the occurrence of a malfunction or the like. Flip be, for stacking the cassette 11, 13 is positioned to the retracted height H4, it is possible to prevent the both are in contact.

  In addition, by adopting such a configuration with sufficient safety measures, the tray transfer stage 16 can be freely moved during the exchange operation of the stacking tray, as in the conventional case. It is possible to eliminate the need to stop the equipment, and realize both reliable safety measures and improved productivity.
